NuTone IM 3003 Master Intercom Cabinet

thingiverse

The NuTone IM 3003 was a very popular intercom system and if your home was built back in the 1990's or earlier it may well have this system installed. If the cabinet was originally white the plastic has turned yellow with age, and because capacitors in the radio have a limited shelf life the radio reception probably isn't that good anymore. It is possible to get the plastic cabinet treated with peroxide and UV light to restore the color, and a number of businesses can repair the radio. One of them has some really good YouTube videos all about this master unit which I found really helpful: https://www.youtube.com/playlist?list=PLsTvqKsBnGYfawSGq6S83HfHIVFZhSVT_ Any realtor will tell you that the smart thing to do with these is remove them from the house and have someone good with drywall fill in the holes. Your third option is to try 3D printing one of these cabinets for the master station. You will need to print one of each part except those with the words "hole filler" in them. I did a lot of trial and error trying to create this cabinet and I really needed to take the unit off the wall so I could make measurements in my workshop. To spare my wife the sight of the hole in the kitchen wall I took one of my first attempts at a cabinet and glued the "hole filler" pieces inside it to create an empty intercom cabinet to replace the original temporarily. You can see what it looks like in one of the pictures. You can glue the parts together with Super Glue. Some work with a small file may be needed to get the parts to fit together properly. When screwing the hinges into the hinge mounts make sure you put them in the right way. The picture showing the hinges did it wrong. If you do it wrong the cabinet won't line up with the box in your wall properly. The cabinet, while usable, could be improved. I ended up making six or so of these before I got something good enough to hang on my kitchen wall. If I thought there was a chance that this design would become popular (or if I was not planning to do the drywall option before the year was out) I would have done at least one more to refine the design.
